Description

A lift for hydraulic support assembly pins

Technical field

The utility model relates to the field of mining auxiliary equipment, specifically a lift for hydraulic support assembly pins.

Background technique

During the installation process of mining equipment, it is common to use a driving vehicle to hoist the components, and then assist in the installation of some equipment components. For example, during the installation and assembly process of a large mining height hydraulic support, the assembly pin is heavy (nearly 200 kilograms) and requires a high lifting height (nearly 3 meters). The traditional way of installing and assembling the pin is to lift the top beam with the main hook of the crane and operate by one person. When the auxiliary hook is used to lift the assembly pin, three people use ropes to pull it, and one person assembles the pin. This is not only inefficient, but also poses great safety risks to equipment and personnel in the process.

Moreover, during use while driving, there are also requirements for space. There must be no obstacles in the space, so a suitable location and angle are required for easy installation. In order to meet the requirements of ready use, lifts are widely used in material handling to save manpower and increase work efficiency. When moving heavy objects, you often need to use a lift.

For example: Chinese patent application number CN202020839832.3 discloses an elevator, which includes a fixed frame, a synchronization device, a driving device and a cargo bucket. The fixed frame includes oppositely arranged guide rails and oppositely arranged fixed plates. The guide rails are respectively located on the fixed plates. At both ends of the fixed frame, the synchronization device includes a relatively arranged synchronous belt, a relatively arranged synchronous wheel and a relatively arranged tensioning wheel. The synchronous wheels are located on both sides of one end of the fixed frame, and the tensioning wheels are located at both ends of the other end of the fixed frame. The tightening wheel and the synchronous wheel are respectively located inside the two ends of the synchronous belt. The cargo bucket is detachably connected to the opposite synchronous belt. The driving device includes a motor and a rotating shaft. The rotating shaft is located between the synchronous wheels and is rotationally connected to the synchronous wheels. The elevator of this utility model drives the rotating shaft to rotate through the motor, the rotating shaft drives the synchronous wheel to rotate, the synchronous wheel drives the synchronous belt to rotate, and the synchronous belt drives the cargo bucket to move, so that the cargo bucket moves more accurately in the fixed frame.

However, the length of the guide rail connected to the lift fixing frame of the above structure is fixed. When lifting goods, it cannot be adjusted in height when passing through the lower door frame, which is inconvenient for lifting. For the lifting and lowering of some shafts, there is a lack of fixed , affects the stability of placement, and it is inconvenient to move the base when it is placed on the ground. It cannot meet the requirements of corresponding installation at any time, and it does not have a good fixation effect, thus affecting the stability during the installation process. There is a definite need for further improvements to this lift.
